13 Introduction General RAID Concepts Correct installation of the disk array requires an understanding of RAID technology and the concepts described in this section. Definition RAID is an acronym of Redundant Array of Independent Disks. A RAID is a Disk Array in which part of the storage capacity is used to record redundant information about the user data stored on the remainder of the storage capacity. The redundant information enables regeneration of user data in the event that one of the Array s member Disks or the access path to it fails. Benefits of RAID 1. Secure Data RAID is an emerging storage technology with the potential to revolutionize the data storage technology. A typical RAID unit contains a set of disk drives, typically two to six, which appear to the user to be equivalent to a single large capacity disk drive. The remarkable benefit of disk array is that if any single disk in the RAID fails, the system and array still continues to function without loss of data. This is possible because the redundancy data is stored on separate disk drives and the RAID can reconstruct the data that was stored on the failed disk drive. 2. Increases system performance As the effective seek time for finding data on a disk can potentially be reduced by allowing multiple simultaneous access of different data on different disks. Utilizing parallel reads and writes of the data spread across the disks in the array, the data transfer rate can be increased significantly over that of a single disk. 3. Easy maintenance RAID system maintenance is typically simplified because it is easy to replace individual disks and other components while the system continues to function. ( Hot swap support ) 1-4

14 Introduction RAID Levels RAID Level 0 : Disk Striping High I/O Performance Improved I/O performance is the major reason of using RAID level 0. No protection is provided against data loss due to member disk failures. A RAID level 0 array by itself is thus an unsuitable storage medium for data that can not easily be reproduced, or for data that must be available for critical system operation. It is more suitable for data that can be reproduced or is replicated on other media. A RAID level 0 array can be particularly useful for : Storing program image libraries or runtime libraries for rapid loading, these libraries are normally read only. Storing large tables or other structures of read only data for rapid application access. Like program images, the data should be backed up on highly reliable media, from which it can be recreated in the event of a failure. Collecting data from external sources at very high data transfer rates. RAID level 0 arrays are not particularly suitable for : Applications which make sequential requests for small amount of data. These applications will spend most of their I/O time waiting for disks to spin, whether or not they use striped arrays as storage media. Applications which make synchronous random requests for small amounts of data. 1-5

15 Introduction RAID Level 1: Disk Mirroring High Data reliability RAID level 1 provides both very high data reliability and continued data availability in the event of a failure of an array member. When a RAID level 1 member disk fails, array management software simply directs all application requests to the surviving member. RAID level 1 is suitable for data for which reliability requirements are extremely high, or for data to which high performance access is required, and for which the cost of storage is a secondary issue. 1-6

16 Introduction RAID Level 3 : Parallel Transfer Disks with Parity High Data Reliability & Highest Transfer Capacity RAID Level 3 technology use a dedicated parity disk to store redundant information about the data on several data disks. RAID Level 3 is an excellent choice for applications which require single stream I/O with a high data transfer rate. RAID Level 3 is optimal for applications in which large block of sequential data must be transferred quickly, these applications are usually of one of these types : They operate on large data objects such as graphical image processing, CAD/CAM files, and others. They are non-interactive applications that process large data sequentially. They usually request a large amount of data (32KBytes or more) with each I/O request. The distinctive performance characteristics of RAID Level 3 : RAID Level 3 provides excellent performance for data transfer-intensive applications. RAID level 3 is not well suited for transaction processing or other I/O request-intensive applications. 1-7

17 Introduction RAID Level 5 : Independent Access Array with Rotating Parity High Data Reliability & Transfer Capacity When RAID Level 5 technology is combined with cache memory to improve its write performance, the result can be used in any applications where general purpose disks would be suitable. For read only or read mostly application I/O loads, RAID Level 5 performance should approximate that of a RAID Level 0 array. In fact, for a given user capacity, RAID Level 5 read performance should normally be slightly better because requests are spread across one more members than they would be in a RAID Level 0 array of equivalent usable capacity. A RAID level 5 array performs best in applications where data and I/O load characteristics match their capabilities : Data whose enhanced availability is worth protecting, but for which the value of full disk mirroring is questionable. High read request rates. Small percentage of writes in I/O load. 1-8

18 Introduction RAID level 5 arrays have unique performance characteristics : The data can be recalculated or regenerated, using parity, when any drive in the array fails. When the failed drive is replaced, either automatically if the subsystem contained a hot spare drive, or by user intervention during a scheduled maintenance period, the system will be restored its full data redundancy configuration by rebuilding all of the data that had been stored on the failed drive onto the new drive. This is accomplished using parity information and data from the other data disks. Once the rebuild process is complete, all data is again protected from loss due to any failure of a single disk drive. 1-9
